    I’ve noticed on the Chinese Covid-19 update website that they are now reporting asymptomatic infection cases, and they are keeping them under medical observation.

    Hi TWiV team,
    I found a paper on aerosol transmission due to speech. They didn’t seem to be able to differentiate much difference between languages. Thanks for another great episode of TWiV!

    “Moreover, measurements of airflow rate during vocalization indicated that certain letters like ‘t’ are associated with higher peak flow rate, consistent with the observed higher peak flow rates for vocalizing words like ‘two’ and ‘ten’ [21]. Our group previously measured the particle emission rate for 30 bilingual participants, reading aloud two translations of the same text, once in English and once in either Spanish, Mandarin, or Arabic [10]. We found no statistically significant difference in overall aerosol particle emissions for any of the four languages; however, the distribution of phones in the translated texts was neither measured nor controlled, so it remains unknown if specific elements of speech, which may be more common in one language than another, are associated with increased particle emission.”
